Hi, I'm new here and about to mod my A10 amp. I understand what parts go where., even if I don't know why they'll work. I work on commercial motors for a living. So high voltage and capacitors are something I work with everyday. The one thing that I don't understand is why you couldn't use a potentiometer instead of a resistor for the schade feedback. My thought is you could tune on the fly for each speaker. Am I missing something? And no I'm not going to try it unless I hear from someone more qualified that it's okay to do.
